Bias adjustment of analog input terminals (, , , , )
To give leeway, the inverter is factory-adjusted by default so that it will not produce an output until a certain amount
of voltage is applied to the analog input terminals.
To reduce leeway, decrease the bias of the analog terminal in use.
Note that specifying a too large value may cause an output frequency to be output, even though the operation
frequency is 0 (zero) Hz.
Gain adjustment of analog input terminals (, , , , )
The inverter is factory-adjusted by default so that the operation frequency can reach the maximum frequency, even
though the voltage and current to the analog input terminals are below the maximum levels.
To make an adjustment so that the frequency reaches its peak value at the maximum voltage and current,
decrease the gain of the analog terminal in use.
Note that specifying a too small value may cause the operation frequency not to reach the maximum frequency,
even though the maximum voltage and current are applied.

Operating a synchronous motor

 ,  : PM motor constant 1
 ,  : Step-out detection current level/ detection time
This parameter is used only when the inverter is used with a synchronous motor. If you intend to use your inverter
with a synchronous motor, contact your Toshiba distributer.

• Function
Four acceleration times and two deceleration times can be specified individually. The selection/switching
mode can be selected from the following 3 options:
1) Selection by means of parameters
2) Switching by means of frequencies
3) Switching by means of terminals
